Combination of the "Tolerance window %, absolute" and "Tolerance window %, relative" parameters
You can combine the "Tolerance window %, absolute" and "Tolerance window %, relative"
parameters as needed. The combined tolerance window (shown in gray in the figure below)
is the maximum of T
rel
and T
abs
.
T = MAX { T
rel
, T
abs
}
ΔI = MAX { ΔI
rel
, ΔI
abs
}
Where (in both formulas above):
●
T = Tolerance, in %
●
ΔI = Maximum deviation of current (+/-)
